[Discuss-gnuradio] Phase errors and expected behavior of in-flight samples when a flowgraph is reconfigured

[Kevin Reid]

I've seen three different intermittent misbehaviors in my application which can 
be described as parallel signal paths getting out of phase with each other. 
(For example, one of them is one stereo audio output channel being delayed from 
the other.)

They all seem to occur when the flowgraph is reconfigured (lock, change 
connections, unlock), even though the subgraph that contains the phase error 
was not itself modified.

Is GNU Radio _expected_ or _known_ to handle reconfigurations poorly in this 
way? Should I treat this as a bug or a feature request?

As a further related question, what is intended to happen to samples which are 
buffered between two blocks (A->B) when that connection is removed? Are they 
discarded, delivered to B, or delivered to whatever A's output is now?)
